In a groundbreaking medical milestone, surgeons at Kenyatta National Hospital (KNH) have successfully performed a complex Gigantomastia surgery on a 17-year-old girl, removing 20.86 kilograms of breast tissue in an 11-hour operation conducted on September 22, 2025.
The procedure marked a significant step forward in Kenya’s medical innovation and offered a new lease of life to Lydia Musivi, who had endured the rare and debilitating condition for over 18 months. The removed tissue accounted for an astonishing 37% of her total body weight.
“This was more than a surgical success it was the restoration of a young woman’s dignity and future,” said Dr. Benjamin Wabwire, Head of Specialized Surgery and Consultant Plastic and Reconstructive Surgeon at KNH, who led the operation.
A Life Transformed
Lydia’s condition had caused rapid breast growth, chronic pain, skin infections, and emotional trauma, forcing her to drop out of school. Following the surgery, she expressed immense relief and optimism:
“The weight is now over. I feel free, lighter, and ready to return to school,” she said.
Her dream now is to return to school and pursue a career in teaching.
A Global Collaboration
The landmark procedure was the result of a multidisciplinary partnership between KNH specialists and experts from Yonsei University in South Korea. The surgical team included Professor Lew, Dr. Kim, and KNH surgeons Dr. Claire Odero, Dr. Agnes Wanjiru, and Dr. Joy Mwangi.
Anaesthesia was led by Dr. Eileen Towett and Dr. Hellen Mwari, with Esther Munga and Eun Jin Chae providing vital nursing support throughout the lengthy operation.
A Mother’s Gratitude
Lydia’s mother, Naomi Mutendwa, shared her emotional journey, recalling years of despair before finally finding help at KNH.
“I watched my daughter disappear under the weight of this illness. It stole her confidence and her future. The KNH team didn’t just treat her they gave me back my daughter and a second chance at life,” she said.
A Testament to Kenya’s Medical Excellence
Dr. Richard Lesiyampe, Acting KNH Chief Executive Officer, praised the operation as a world-class achievement and a testament to Kenya’s growing capacity for advanced surgical care.
“We are solving local health challenges with global standards of innovation and compassion, setting new benchmarks for patient-centred care,” he stated.
Lydia has since been discharged and is recovering at her home in Mwingi, Kitui County, with plans to resume school in January 2026.
